Find notes related to a given note based on shared links, shared tags, or both. Returns a ranked list of related notes with similarity scores.
AI agents call palace_related to retrieve information from Obsidian Palace MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
palace_related performs read-only operations: it searches for and retrieves related notes based on existing metadata (links and tags) without creating, modifying, deleting, or executing any operations. The tool simply returns information, making it a Read category tool with low severity since misuse would only expose existing knowledge from the user's vault without enabling data modification or external actions.
From the tool's definition Tool description states it 'Find notes related to a given note' and 'Returns a ranked list of related notes with similarity scores.' These are query and retrieval operations with no side effects.
